"This has put me in a fix. On principle, I want employees to have time with their families, but I want to save money for my family. If there is a great deal on a computer or tablet, I might be lured to go out after dinner."

Jenny Martinez says retailers have spoiled the fun.

"They have ruined it," says Martinez, of Hollywood. "It used to be fun to wake up at 5 a.m. [Friday] and go to Target. Then, it was midnight, then 10 p.m. Now, it's just too early."

Martinez and her husband usually do all their Christmas shopping on Black Friday.

"We can't participate now," she says. "I have young kids, so I can't go out in the middle of the day on Thursday."

There is no need to.

Lots of stores are bucking the trend, opening on Friday. Plus, those with Thanksgiving hours are offering deals on Friday, too.

Traditionalists can still get an early thrill on Friday. Home Depot and Lowe's will open at 5 a.m., Staples at 6 a.m.; BJ's at 7 a.m.; and Nordstrom, Costco and GBS Beauty at 9 a.m.

BrandsMart has extra inventory no matter what time you arrive. Walmart will hold an 8 a.m. sale on Nov. 29. Shop after midnight on Nov. 29 at Target and get a coupon for 20 percent off a total purchase good on Dec. 1-7 if you spend $75, according to a Black Friday preview ad on Target.com.

For shoppers who worry about retail workers, Target and Macy's said in statements they let staff volunteer for preferred shifts in advance. Walmart is giving associates on holiday duty free meals and 25 percent off holiday purchases.
